Fiat Fiat Oil Specifications

These qualifications define the characteristics to be complied with by the lubricants used in engines with Otto and Diesel cycle for the first time of filling and during service. The standard is formed of a series of tests in the laboratory and on the engine to assess the performance level of lubricants. The laboratory tests qualify the lubricant evaluating the viscosity, cold yield value, tendency to produce foam, corrosion on copper reed, behaviour with rubbers and resistance to oxidisation. The engine tests assess the performance levels of lubricants in terms of sticking rings, deposits on pistons, wear and also oil consumption of certain diesel and petrol engines which are the most representative of Fiat Auto’s most advanced technologies.
